Is our sub fee not enought

So, with each passing month, the game's profits are only growing more and more.

That's not how businesses calculate profits >_>
Though in fairness, that is a clever marketing trick to claim your product is more profitable than it actually is, because semantically you're right: The sum of profits is increasing, therefore the product becomes more and more profitable. Which in turn makes Space Invader the most profitable game out there - Screw WoW and League of Legends!

When an investor/shareholder reads "more and more profitable" however, he expects the yearly/quarterly profits to become higher and higher, not the sum of them. And that means you need to make as much profit as in the last reporting period plus something extra. That's how profit is usually understood in business.

It might be that the person I was replying to meant the more misleading definition - in that case, naturally my arguments hold no water. I simply assumed the more common definition was used.
